Status LEDs
Each time Network Camera starts, it will perform a Power-On Self Test, abbreviated as POST hereafter,
to examine every hardware module. As soon as the administrator plugs in the power adapter, both LEDs
under the network LED will flash one by one until the POST is done. If any module fails, both LEDs will
indicate to the users the error according to the pattern listed in Appendix A. If the result is good, both
LEDs will turn off for a while and then follows the pattern below. Network interface depends on the
peripherals including Ethernet UTP cable, modem or null modem cable. If the Ethernet cable between
Network Camera and Ethernet hub is good, Network Camera will choose the Ethernet network. If
Ethernet is unavailable but a operational modem is connected, the network interface will be PPP with
modem. If either of the above is not the case, Network Camera will try the interface of PPP with null
modem.
